Description

STM*1 DXC 1?Overview
The F*****5SH is an optical HUB equipment that features a compact, bidirectional SDH structure. It provides two slots for inserting the HUB**5 cards; each card provides 8 downlink STM*1optical interfaces (OPT**8) and 2 uplink STM*1 optical interfaces (OPTA/B). A single card can realize DXC function among the services over *0 optical interfaces, with DXC capacity of **0 * **0 VC*2. It is suitable for big companies in their applications of data access and interconnection of base stations. HUB****2D supports CLI management based on RS**2 and TELNET, the SNMP_V1 and SNMP_V2 protocols, as well as the C/S-structured network management platform RAYVIEW, implementing configuration, management, and maintenance for the entire complicated network.
2?Features
?1U Height, *9 inches Width. Two slots can be used for inserting up to two HUB**5 cards.
?SupportsTU**2granularity cross-connection
?(DXC).
?Service Interface
• Up to 4 STM*1 uplink optical interfaces (OPTA/B) (2 interfaces per card).
• Up to *6 STM*1 downlink optical interfaces (OPT**8) (8 interfaces per card).
• Employs LC-type SFP optical transceiver; supports hot-swap function and real-time monitoring for the status of optical modules. Uses single-mode fiber, with selectable transmission distance of*5km,*0km, and*0km.
• Optical interfaces support ALS and RPD functions.
• Optical interfaces support outward loopback on line side and TU**2 channel outward loopback.
• All characteristics of the optical interfaces comply with GB/T*********5 and ITU-T G.**3.
?Auxiliary Interfaces
• Each card provides an Ethernet management
interface : EMU (RJ*5 connector).
• Each card provides a RS**2 management
interface: CON (RJ*5 connector).
• Each card provides two external synch clock I/O interfaces?ETS1, ETS2 (RJ*5 connector).
• An UALM / DALM (urgent / non-urgent alarm) output interface: U/DALMO (DB9 connector).
?Protective function
• Supports SNCP(subnet connection protection) function.
?Timing Mode
• Independent timing for HUB**5 cards or unified timing by interconnecting via the uplink optical interfaces or ETS interface.
• Supports four timing modes: free oscillation, tracking, locking, and holding-up. All of them can be switched either automatically or forcedly by hand.
• “Tracking internal timing source” is selectable and complies with ITU-T G.**3 standard.
• Timing sources(T*1, T*2) for tracking uplink STM*1 optical interfaces (OPTA/B) are selectable.
• “Tracking external synch timing source (T*1/T*2)” is selectable, with rate of 2.**8 Mbit/s.
• Supports “external synch timing source output (T*1/T*2)”, with rate of 2.**8Mbit/s.
• “Auto-selection” or “selected by hand” can be set for the timing reference source according to its alarms, frequency offset, SSM ranks, as well as its priorities.
?Equipment Management
• Supports one network management mode**- Star Embedded DCN.
• Supports CLI management based on RS**2 and TELNET. CLI supports the control over local equipments only and cannot manipulate other NEs in the network.
• Supports SNMP_V1 and SNMP_V2 protocols; supports the PC-based, C/S-structured network management platform RAYVIEW, implementing configuration, management, and maintenance for the entire network.
• Supports FTP files transmission protocol; realizes on-line upgrade for the embedded software, and configures data to perform the upload / download operations.
?Provides dual **8V DC power interfaces; Support hot backup, prevents inverse connection and surge occurrence.
?Maximum power consumption is less than *0W.
